Asymmetric Tread Pattern Tire Specification Example for Assembly Programmes: Quick Fit Version
Asymmetric Tread Pattern Tire Specification Example for Assembly Programmes: Quick Fit Version
This is a worked specification for asymmetric tread pattern tire in a quick fit version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The quick fit version version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.
Example specification
| Item | Asymmetric Tread Pattern Tire |
|---|---|
| Application | Assembly Programmes |
| Version | Quick Fit Version |
| Base material | Reinforced Nylon |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Finish | zinc plated |
| MOQ | 3,000 pieces per specification |
| Sampling | 7 working days, 5 days per revision |
| Compliance | DOT |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Reinforced Nylon, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- surface grinding
- anodising
- robot welding
- powder coating
- sintering
- heat treatment
Where this example applies
Programmes that run quick fit version most often specify this build for assembly programmes. Related applications include municipal fleets, delivery vans, three-wheelers, city buses, emergency vehicles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the DOT-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
